Angle displacement measurement device

Abstract

The invention discloses an angle displacement measurement device, and belongs to the field of aviation testing design. The device comprises a parallelogram mechanism formed by the hinged connection of four connecting rods. One side of the parallelogram mechanism is disposed on a measured object (9), and the opposite side of the parallelogram mechanism is provided with a slide rail (10) which is provided with a rocker arm (5), wherein the rocker arm (5) can be rotatingly connected to an angular displacement sensor (6). The device enables the rotation of the measured object (9) to be transmitted to the angular displacement sensor (6) through the parallelogram mechanism, and achieves an effect of achieving a measurement purpose without measuring the position of a rotating shaft of the measured object (9). The position of the device on the measured object (9) can be adjusted freely, and the fixing position of the angular displacement sensor (6) also can be adjusted freely, so the angular displacement sensor (6) can measure the angular displacement in different environments under different conditions through the same measurement assembly.

Description

technical field [0001] The invention belongs to the field of aviation test design, and in particular relates to an angular displacement measuring device. Background technique [0002] In the field of industrial design, especially the test process in the field of industrial design, many problems involving angular displacement measurement are difficult to solve, such as the deflection angle of the aircraft rudder surface. It is required to measure the angular displacement of the moving parts in real time. The installation method and measurement method of the angular displacement sensor are strict. For multiple measurement points with different working conditions and different spaces, the cost of designing and processing the sensor fixture is very high. And the current general measurement methods all need to accurately measure the position of the rotating shaft first, and for some assembled products, the rotating shaft of the tested part is inside the product, which cannot be a...

It is required to measure the angular displacement of the moving parts in real time. The installation method and measurement method of the angular displacement sensor are strict. For multiple measurement points with different working conditions and different spaces, the cost of designing and processing the sensor fixture is very high. And the current general measurement methods need to accurately measure the position of the rotating shaft first, and for some assembled products, the rotating shaft of the tested part is inside the product, which cannot be accurately measured, resulting in inaccurate measurement results

At present, there is no general-purpose device that can meet the requirements of various working conditions
